  APA Engineered Wood Products

APA ENGINEERED WOOD CONSTRUCTION GUIDE

Size: 13 MB

[align=center][img][Image: 58260390811892315869.jpg][/img]

In searching the forum I found that one of the main material used these days (plywood) does not have enough space.
One of the major association globally is "APA Engineered Wood Association"
I will try to put some information here.

A Short History of APA

APA — The Engineered Wood Association is the nonprofit trade association of the U.S. and Canadian engineered wood products industry. Based in Tacoma, Washington, the Association is comprised of and represents manufacturers of structural plywood, oriented strand board (OSB), structural composite panels, glued laminated (glulam) timber, wood I-joists, and laminated veneer lumber (LVL). (See the glossary backgrounder for explanation of these products.)

APA was founded in 1933 as the Douglas Fir Plywood Association to advance the interests of the burgeoning Pacific Northwest plywood industry. Adhesive and technology improvements eventually led to the manufacture of structural plywood from Southern pine and other species, and in 1964 the Association changed its name to American Plywood Association (APA) to reflect the national scope of its growing membership.

The Association’s membership expanded again in the early 1980s with the introduction of oriented strand board (OSB), a product the Association helped bring to market through development of new panel performance standards. A decade later, APA formed a related nonprofit organization now called Engineered Wood Systems (EWS) to accommodate manufacturers of non-panel engineered wood products, such as glulam timber, wood I-joists and laminated veneer lumber.

To better reflect the broadening product mix and geographic range of its membership, the Association changed its name again in 1994 to APA—The Engineered Wood Association. The acronym “APA” was retained in the name because it was so widely known and respected in the marketplace.

Today, APA and EWS represent approximately 152 engineered wood product mills in the U.S., Canada and abroad.

Utilization of multimode Love wave dispersion curve inversion for geotechnical site investigation

Author: La Hamimu, Mohd Nawawi,Jamhir Safani | Size: 1.5 MB | Format: PDF | Quality: Original preprint | Publisher: Journal of Geophysics and Engineering, Volume 8, Number 2 | Year: June 2011 | pages: 11 | ISSN: 1742-2132

[Image: info.png]
Inversion codes based on a modified genetic algorithm (GA) have been developed to invert multimode Love wave dispersion curves. The multimode Love wave dispersion curves were synthesized from the profile representing shear-wave velocity reversal using a full SH (shear horizontal) waveform. In this study, we used a frequency–slowness transform to extract the dispersion curve from the full SH waveform. Dispersion curves overlain in dispersion images were picked manually. These curves were then inverted using the modified GA. To assess the accuracy of the inversion results, differences between the true and inverted shear-wave velocity profile were quantified in terms of shear-wave velocity and thickness errors, ES and EH. Our numerical modeling showed that the inversion of multimode dispersion curves can significantly provide the better assessment of a shear-wave velocity structure, especially with a velocity reversal profile at typical geotechnical site investigations. This approach has been applied on field data acquired at a site in Niigata prefecture, Japan. In these field data, our inversion results show good agreement between the calculated and experimental dispersion curves and accurately detect low velocity layer targets.

This report summarizes part of a four year study on the feasibility and limitations of a small scale model studies in earthquake engineering and practice. The emphasis is placed on dynamic modeling theory, a study of mechanical properties of model materials, development of suitable model construction techniques and an evaluation of the accuracy of prototype response prediction through model case studies on components and simple structures. Steel and Reinforced concrete structures are considered in this study.

Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the management of surface water and groundwater resources. Meeting the challenges and the impact of climate change on water resources is also discussed in the book. Most chapters give insights into the interpretation of field information, development of models, the use of computational models based on analytical and numerical techniques, assessment of model performance and the use of these models for predictive purposes. It is written for the practicing professionals and students, mathematical modelers, hydrogeologists and water resources specialists.

Interpretation Procedure for Pressuremeter Tests in Sand

Author: Ilan Juran & Behnam Mahmoodzadegan | Size: 0.9 MB | Format: PDF | Quality: Unspecified | Publisher: Journal of Geotechnical Engineering vol 115, issue 11 | Year: 1989 | pages: 1617-1632


[Image: info.png]

A new approach for the interpretation of pressuremeter tests in sands is proposed that permits the determination of shear strength characteristics, dilatancy properties, and shear modulus from the analysis of pressuremeter test results. A relatively simple soil model has been developed that takes into account the contracting or dilating behavior of the soil, or both, during the pressuremeter cavity expansion. The soil is assumed to be an elastoplastic material with a nonassociated flow rule. To evaluate the proposed interpretation procedure, laboratory cavity expansion tests on Fontainbleau sand specimens have been conducted in a specially designed hollow-cylinder cell. The comparison between the sand properties (shear modulus, peak friction angle, dilation angle) derived from the cavity expansion tests and those obtained from conventional tests illustrates the applicability of the proposed interpretation procedure.
